How to Programmatically Convert PDF to PDF/X with pdfRest

Here's a simple example of how to use cURL to send a request to the pdfRest API to programmatically convert a PDF to PDF/X-4:

curl -X POST "https://api.pdfrest.com/pdfx" \
  -H "Accept: application/json" \
  -H "Content-Type: multipart/form-data" \
  -H "Api-Key: YOUR_API_KEY" \
  -F "file=@/path/to/your_document.pdf" \
  -F "output_type=PDF/X-4" \
  -F "output=print_ready_document"

Replace YOUR_API_KEY with your actual pdfRest API key and adjust the file path. You can specify `PDF/X-1a`, `PDF/X-3`, `PDF/X-4`, or `PDF/X-6` for the `output_type` parameter.
